[RE-wrenches] Mounting on rock

[Ray]

We've welded a flanged plate to the bottom of the pole and then set 
epoxy anchor bolts into the rock.  Another option we've tried is drill a 
8" hole into the rock to get the base of the pole a foot down into the 
rock and then poured a reinforced block of concrete on top of the rock.  
smaller holes were drilled into the surrounding rock to attach the 
concrete to the rock as well.

Ballasted systems could be an option, as well as low profile racking 
with multiple anchor points.  Not fun but it can be done.
